Yep.. Just finished my Meta 42 amp. Didn't order the PCB from tangent as I felt I could do it on my own..
Want to say thanks to everyone who was involved in the designing of the amp!
YES, ppl, that includes you!
The difference between my amp and the schematic would be that I'm using:
0.22uF Evox PMR (Metalized polyprop) in parallel with 0.022uF Evox PFR (Poly film w/ metal foil for high speed apps) for my C1. (as advised by puppyslugg)
1M ohm resistor for R2.
I cannot get the TLE2426 voltage splitter so I'm using 2 22K ohm resistors. Removed the diodes because I was having problems using them. Didn't have the patience to troubleshoot the thing.
Using some generic 50K ohm ALPS dual-pot. I say generic because it's by ALPS but not a Blue velvet or Black Beauty. Farnell sells the latter but it's way too pricey (S$63==US$35) for a poor student like me.
The op-amp's are OPA134PA IC's. The only op-amp I can find. The AD823 would have to be ordered from Farnell if I wanted them. Only 2 choices.
Using EL2001CN buffers; Not stacked because I couldn't afford much of these. They're the most expensive single component in the amp.
Total cost of the amp: about S$100 (US$56). Could have been lower but I needed to replace some parts here and there. Like defunct RCA jacks and my older 1/4" jack. (supposed to be from Neutrik according to some website; Cheap stuff.. Only about S$1.50)
